Specification of Letters Patent.

Patented Mar. 23, 1920.

Application filed. August 23, 1918. Serial No. 251,111.

To all whom it may concern:

Be it known that I, lsAoonn PoMnuANrz, a citizen of the United States, residing at Kansas City, in the county of Jackson and State of Missouri, have invented certain new and useful Improvements in Reinforced Door-Frames and Ladders; and I do declare the following to be a full, clear, and exact description of the invention, such as will on able others skilledin the art to whichit appertains to make and use the same, reference being had to the accompanying drawings, and to the letters and figures of reference marked thereon, which form a part of this specification.

This invention relatesto an improved builtup structure in which tile or similar building units are employed.

The invention has reference particularly to silos, and among the objects is the provision of means for constructing an improved reinforced door opening frame including novelly constructed jainlo blocks and ladder construction. By employing my invention in silos and the like, the door opening may be'constructed so as to have a uniform width throughout. The jamb blocks are shown as constructed with off-set mem bers through a portion of their widths so as to provide means to insure the proper overlapping joints in the layers of tile. The jamh blocks are also provided with angle receiving recesses to position the angles which constitute the Lip-rights for the ladder and these angles may have sockets constituting means for positioning the rounds for the ladder as well as to provide means for securing the door boards in looking positions to close the openin framed by the angles.

In the drawings 1 have illustrated the preferred form of silo construction in which.

my invention is involved.

Figure l is fragmentary view of the silo showing the jamb blocks and ladder andreiii-forcing angles in place.

Fig. H is a detail. view of one of the jamh blocks.

Fig. III is a cross sectional view through the silo door at the opening, showing a top plan view of one course of the tie blocks.

Fig. IV is a fragmentary perspective view of a door opening showing a part of the door in looking position.

Fig. V is a longitudinal sectional view through one of the rounds and a socket for receiving the angle, "being shown in cross section.

Fig. VIis a cross sectional view through a silo, showing a slightly modified form of ladder, one course of tying blocks being shown in plan.

Fig. VII is a detail perspective view showing the modified arrangement for attaching the round to the angle.

Fig. VIII is a detail perspective view of a pivoted round.

Referring now to the drawings by numerals of reference:

1 designates j anrb blocks which are arranged end on end invertical relation, on each side of the door opening 2. The detail construction of the iamb block is best shown in ll as comprising a rectangular body 8 h avinp; an off-set member 4: at one edge and an angle receiving; groove 5 at the other edge, adjacent to the groove 5 is a shoulder or recess 6 to receive the door boards 7. The angles 8 and 9 are positioned vertically in the grooves 5 with inwardly projecting flanges 10 and 11 and at suitable points along the portions seated in the grooves are sockets 12 alining; with elongated openings 13.

The built up structure contemplates the utilization of reinforcing rods 14 which are positionedbetween the layers of tile and in the preferred form, these rods are adapted to pass through-the elongated openings 13 in the angles. The shape of the openings permits them to be in line with arod irrespective of the fact that the two courses on opposite sides of the opening are not in perfoot alinement or in the event that the center of the cement is not in register with the center of the openings.

If the openings 13 were round or the same size in diameter as the rods, difficulty would be experienced in erecting the ladder hecause the cement between some of the courses might varv in thickness, and in that event the openings 13 would not be in position to receive their respective rods. With the construction shown, however, the rods might be slightly eccentric with respect to the sockets 12 without any disadvantage. The sockets 12 are adapted to receive the rounds 15 of the ladder, the rods 14 passing through these as heretofore explained, the rounds being securely supported by the sockets 12.

It will therefore be seen that an efficient ladder construction is provided, which also serves as a door opening frame and that the door opening will be of uniform width throughout as assured by the rounds 15 which serve as spacers.

When it is desired to secure the door opening boards in place, the edges thereof may rest in the recesses formed by the shoulders 6 and the latch plates 16, or the bolts 17 may be overlapped and bear against the flanges 10 and 11 of the angles, the same being'secured by the wing nuts 18. The offset members 4L constitute abutments whereby the laying of the tile in staggered relation to provide overlapping joints is assured as will be apparent by referring to Fig. III.

From the foregoing it will be obvious that the built up structure, such as a silo, may be conveniently constructed with all of the parts efliciently tied in and that the proper spacing for the door opening, etc., will be assured.

By reference to Fig. VI it will be observed that the outer blocks and the inner blocks are staggered with respect one to the other, or provided with break joints, so that the inner wall blocks project slightly beyond the outer wall blocks to fit into the offset portions of the jamb blocks and thereby assist in providing stability for the structure about the door opening.

The tying blocks adjacent to the jamb blocks may be cut away or formed with ofl set portions to make them fit the off-set portions of the jamb blocks. Of course, especially formed blocks may be provided but ordinarily, the same type of tie blocks will be employed, the operator cutting away portions from the outer faces through about one-half the width of the block so that the off-set portions 1- of the amb blocks will fit therethrough.

In the form shown in Figs. VI and VII, the same general characteristics prevail, but in this form the tie rods 14 do not extend across the opening but are secured to the angles at 19 by the nuts 20.

The rounds 21 which form the steps for the ladder are here shown as consisting of pipes or tubes having their ends 22 and 23 flattened and riveted to the imminently proectmg portions 10 and 11 of the angles. In other respects the construction is similar to that illustrated in Figs. I to V both inclusive.

In Fig. VIII I have shown a round 24 pivoted at 25 to one angle and having a hooked end 26 adapted to engage an eye 27 in the opposite angle. The pivoted rounds 2 1 may alternate with the fixed ones and are adapted to have a vertically swinging movement so as to permit the available opening to be enlarged for the purpose of removing ensilage from the silo. Normally, however, the rounds 24 will be hooked in place.

Having thus described my invention what I claim as new therein and desire to secure by Letters-Patent, is:

1. In a built-up structure having a door opening, vertically arranged jamb blocks framing the door opening, the jamb blocks having alining vertical grooves or recesses, angles seated in said grooves and provided with longitudinal slots to adjustably receive reinforcing rods included in the built-up structure, and ladder rounds connected to the angles.

2. In a built-up structure having a door opening, vertically arranged jamb blocks framing the door opening, the jamb blocks having alining vertical grooves or recesses, angles seated in said grooves and provided with longitudinal slots to adjustably receive reinforcing rods included in the built-up structure, socket members secured to the angles and surrounding the slots, and hollow ladder rounds supported by the sockets.

3. In a built-up structure having a door opening, vertically arranged jamb blocks framing the door opening, the jamb blocks having alining vertical grooves or recesses, angles seated in said grooves and provided with longitudinal slots to adjustably receive reinforcing rods included in the built-up structure, socket members secured to the angles and surrounding the slots, hollow ladder rounds supported by the sockets, and additional ladder rounds carried by the angles.

4. In a built-up structure having a door opening, vertically arranged jamb blocks framing the door openings, the jamb blocks having alining vertical grooves or recesses, angles seated in said grooves and provided with longitudinal slots to adjustably receive reinforcing rods included in the built-up structure, socket members secured to the angles and surrounding the slots, hollow ladder rounds supported by the sockets, and additional ladder rounds carried by the angles, the-sockets being supported by the portions of the angles in the grooves and the additional rounds being carried by the other flanges of the angles.

5. In a built-up structure having a door opening, vertically arranged jamb blocks framing the door opening, each jamb block having a shoulder at one edge and a recess at the other edge, the shoulder overlapping the blocks of the bui1t-up structure and the recesses facing the door opening, vertically arranged angles in the recesses in the jamb blocks and haying elongated slots, reinforcing rods in the built-up structure projecting through the vertical slots and extending across the door opening socket members carried by the angles and surrounding the slots, and hollow ladder rounds carried by the sockets and inclosing the portions of the reinforcing rods which extend across the 10 opening.

In testimony whereof I afiix my signature.
